Position will be measured on the y-axis and time measured on the x-axis. Usually y is meters and x is time so when you take the slope (velocity or speed) y/x = m/s.
Answer:
W = 2038400 J
Explanation:
Let
water be Δx meters thick at the depth of x.
So it has volume(V) of 6x.Δx
Now we know that weight of the water is given by
W = ρgV
=1000 x 9.8 x (6x.Δx)
It is also know that the water is lifted to a distance of (7-x)
Therefore, work done is
W =
=
=
=
= 58800 x 34.667
= 2038400 J
Answer:
if one wave has a negative displacement, the displacements would be opposite each other, so the displacement where the waves overlap is less than it would be due to either of the waves separately.
-causes a moment where the net displacement of the medium is zero. energy of waves hasn't vanished, but it is in the form of the kinetic energy of the medium
-then both emerge unchanged
Explanation:
Answer:
Explanation:
Given
Distance between source and receiver
Sound Intensity
Distance of of second observer
Intensity varies as
using this
The molten iron has currents of its own, just like an ocean, and these moving currents create the magnetic field. But the currents are not consistent and the Earth's magnetic field moves around, with the magneticnorth pole currently drifting by about 10 miles a year.
